I updated my templates fedora-26 to 27 and after to 28. The docs are here: https://www.qubes-os.org/doc/template/fedora/upgrade-27-to-28/
About the conflict with dconf, I included -x dconf to the upgrade dnf command. After that I did: sudo dnf update --allowerasing --best --enablerepo=qubes-vm*-current-testing So far, it is working ok. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
